What is the life expectancy for individuals with chromosome 1p36 deletion syndrome?

The severity and nature of signs and symptoms of chromosome 1p36 deletion syndrome varies between affected individuals, so it is difficult to predict the long-term outlook for an individual child.[1][2] Generally, affected individuals do survive well into adult life.[1] There has been one study to date in which the course of 1p36 deletion syndrome was investigated, with a follow-up spanning 18 years. Although this study does not specifically address life expectancy, it does contain substantial information regarding the natural history of the condition.
